Been using this for years, no complaints

Honestly for 2025 you really want to look at the underlying models because that’s what actually does the heavy lifting and right now Claude 3.5 Sonnet is basically the gold standard because its prose feels way more human and less robotic than most others plus its 200k context window is CRITICAL for a novel so you dont have it forgetting your plot points halfway through. If you arent super tech-savvy though you might find Sudowrite better since it's a wrapper that uses multiple models like GPT-4o but gives you actual buttons for "expanding" or "rewriting" scenes which is SO helpful. Tbh the technical side of managing tokens and context window decay is annoying for a beginner so having a dedicated interface helps a lot because idk if you want to be manually feeding it "memory" chunks every few thousand words to avoid hallucinations. I've noticed GPT-4o has better logic for plotting out complex character arcs and hard magic systems but Claude definitely wins on the actual creative writing flow and dialogue

tbh i totally agree about Claude being the goat for prose right now but if youre watching your budget you should definitely look into OpenRouter because paying a flat subscription fee every month can get really expensive if you have a slow week and dont write much right? With the API you just pay for what you use and its usually way cheaper in the long run. Also if you want that user-friendly vibe without the high price tag of some all-in-one tools you should check out NovelCrafter since it lets you plug in your own API keys and it has a built-in codex to keep your character bios and world-building notes organized so the AI doesnt hallucinate as much and you arent wasting money on tokens re-explaining who your protagonist is every five minutes it basically pays for itself. TL;DR: Use OpenRouter to pay only for the words you write and pair it with NovelCrafter to stay organized on a budget.
